The typical method for diagnosing diabetes is through a blood test. This approach is based on measuring the level of glucose in a person's blood, which provides crucial information about their blood sugar control. The most common tests include the fasting plasma glucose test, the oral glucose tolerance test, and the hemoglobin A1c test. Each of these tests can indicate whether an individual has diabetes or is at risk of developing it by assessing how well the body is managing glucose levels over time.

Blood tests are preferred because they offer a more accurate and immediate indication of glucose levels compared to other methods. While physical examinations, urine analysis, and family history assessments can provide helpful context and may indicate potential diabetes-related issues, they do not establish a definitive diagnosis of diabetes. Blood glucose monitoring is essential for confirming the presence of the disease and determining appropriate management strategies.
